Aloe pembana

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Aloe pembana faces severe threats from habitat destruction due to agricultural expansion and urban development on Pemba Island. The species' extremely limited range makes it particularly vulnerable to localized disturbances, while collection for horticultural trade has further reduced wild populations. Climate change poses an additional threat through altered rainfall patterns affecting this drought-adapted succulent.

Threat summary
